Heavy rains are expected to cause flooding in low-lying areas in North Jersey and muddy up the morning commuter for residents.

The National Weather Service issued a flood advisory from 6:05 to 8 a.m. on Wednesday, smack dab in the middle of the morning rush hour for commuters. The advisory encompasses Bergen, Hudson, Passaic and Essex counties.

At 6:15 a.m., Route 80 West was flooded, with cars slowing to a crawl. One car had stopped on the shoulder of the road. Others hydroplaned as they traversed the busy highway.
